Has Duke and Missouri already completely destroyed your NCAA brackets? Do you have any idea what that means? Well, non-sports fans can still get in on the March Madness fun, but instead of basketball, why not try the 'Game of Thrones' tournament (aka "Westeros Madness")?

How it works is that fans of the show vote on which characters in the fantasy series move on to the next round. (Don't worry, it has no real effect on the show. It's just for fun.) The criteria is the character's "intrinsic worth." While that is something that can be difficult to quantify, in a sense that's what this crowd sourcing exercise is doing.

The 32 character bracket has already been whittled down to the Sweet 16. First round upsets include two seed Joffrey Baratheon falling to seven seed Renly Baratheon. You have until March 20 to decide who gets to advance to the Elite Eight.

The champion will be crowned  on April 1, which is also when season two of 'Game of Thrones' premiers on HBO. But before you download your own form, check out the season 2 trailer below and see if you can come up with your own strategy.
